Several years ago, at the American Cheese Society conference, I met a young woman who told me she planned to open a shop in San Francisco selling only domestic cheeses. Not smart, I thought. How could a cheese business survive without the European classics? Well, six years in, Sarah Dvorak’s Mission Cheese is so successful that it now has a Berkeley sibling—bigger, more ambitious and likely to launch a national trend. Shouldn’t every community have its own cheese bar?
